The B13 template fix only fixed fresh ISOs. Already-deployed nodes keep their
old nginx config, where /app/fedimint/ proxies to :8175 without rewriting the
Guardian UI's root-rooted asset URLs (src="/assets/...", url("/assets/...")).
Those resolve against the SPA root: bg-network.jpg exists there by luck, but
app-icons/fedimint.jpg 404s (location /assets/ uses try_files =404) — the
visibly-broken icon.
bootstrap.rs::patch_nginx_conf now heals both paths on startup:
- Style A (main conf, HTTP): swaps the old single nostr-provider sub_filter tail
for the full reroot set; byte-matches the shipped template.
- Style B (HTTPS app-proxy snippet): the snippet's fedimint block has no
sub_filter and a per-node-varying trailing directive, so anchor on the unique
:8175 proxy_pass and insert the reroot set after it (nginx ignores directive
order). Snippet added to the bootstrap nginx loop (skipped on HTTP-only nodes).
missing_* flags are now gated on their splice anchors so the included snippet
neither attempts the main-conf-only patches nor logs warn-skips every boot.
Idempotent via the 'href="/' 'href="/app/fedimint/' marker.
Verified on .198 (both paths): fedimint app-icon 404 -> 200 image/jpeg; nginx -t
OK; containers survived restart (Quadlet); idempotent steady state, no warn spam.
